ABSTRACT:
In a device for the electric measurement of the level of a liquid in a container, particularly in the gasoline tank of a vehicle, a support developed as protective tube of a conductor foil is fastened for swinging against the force of a spring (14 and 21) to the top of the container. In order to be able to arrange the support even in containers in which the point of attachment of the support is lower than the highest level to be detected, the support is subdivided into three approximately rigid sections, (2, 3, 5) each two sections (3, 5) being articulated in the manner of a toggle joint to each other and being under spring action. In this way the outermost section (3) is swung, substantially independently of the inside height of the container, on the one end towards the bottom (4) and on the other end towards the top (1) of the container.
